ful improvements in the art of printing, and has particularv reference to a mechanism and an improved method in the printing art ,which embodies means including specially improved leads or liners comprising spacing material generally utilized in forms to prevent the furniture and the units of the printing form from workingup thus causing smudge or markings on the sheet being printed. r,

The principal object of the present invention is the provision of a liner or lead for the printing art that embodies means for preventing the buckling or arching of the lines or units of the form.

Another object of the invention is the provision of a device of the class described that will take place of the make-shift card board inserts generally used in present practice. A further object of the invention is to provid a device of the class described that is designed to be utilized in connection with all kinds of so called furniture, whether of wood or metal, and in connection with all articles commonly utilized in the art to secure the units of these forms in as; solid a condition as possible.

A still further object of the invention is the provision of a liner or lead for the purpose specified that prevents buckling up of the form and also provides: a simple and economical preventive of this cause and at the same time provides efficient means that may be readily and quickly applied to obviate the present make-shift material generally utilized for this purpose.

- Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, 7 V 1 Fig. 1 represents a perspective view of my improved strip or lead per se;-

Fig. 2 is an end elevation of the same;

on the line 3-3 of Fig. 1;

Fig. 4 is an extorted view showing the general form or arched position of a form which is overcome by the use of the improved liner; and

Fig. 5 is a diagrammatic View illustrating the placement of the improved device in positionas it would appear in actual use between the units, and.

Fig.6 is a fragmentary detail perspective of a modified form of strip to that shown in the a remaining figures.

I-Ieretofore, ithas been .the custom to cut narrow strips of cardboard and push the same bepassed through the press, but also causes loss of tween the units, in order to provide a wider spacing overall at the bottom of the form, in order to-qvercome the tendency of the units to fbuckle upward or archf. This buckling of the form being caused by the form being improperly locked up, 5 or the pages or units not being justified uni- V formly, or in the case of slugs of linotype being cast under at'the top ratherthan at the bottom, or from other causes.

The result of this procedure is that the spacing matter of whatever character has a tendency to work up above the surface of the type face and thus imprint a smudge upon the sheet being printed. This not only spoils every sheet that is 15 time, and great annoyance, as the press must be stopped and the piece of furniture, slug, or other article forced back to its proper place, only to have the smudge upon the sheet again appear at intervals.

The present invention overcomes the obstacles set forth by the utilization of a strip of metal 6, preferably of brass, of the usual height of spacing material, or preferably two-points thick, or in other words, one-thirty-sixth of an inch thick,

the length of said strip being governed by the length of the form required.

This strip comprises in detail a right angle flange 1 formed at its upper end and a longitudinally formed groove 8 pressed outwardly adjacent its lower edge, as clearly disclosed in Figs. 1, 2, 3, and 5. 7

Immediately above the groove and arranged slightly above the groovea series of punched out lips 9 are formed, these lips together with the groove 8 forming the bead providing spacing and gripping members to prevent the upward movement of the linotype slugs ll], caused by the impinging action of the projecting lips 9.

In Figure 6 a slightly modified form is shown in which the bead or bulge 8 is shown without the projecting lips 9, as in Figs. 1, 2, 3, and 9. Fig. '3 is a transverse section of the same taken 7 In Figure 4 I have'repr'esented a series of linotype slugs which have been cast and trimmed slightly at the top, causing a decided bulge, or arch, in the page of metal, and causing the lines thereof to be off their feet, and in Figure 5 I have shown the same page as it would appear after the introduction of the strips constituting my invention with the bulges or grooves 8 at the bottom, thus equalizing the pressure and overcoming the arching of the metal and causing all lines, or slugs, to rest equally or evenly upon their feet.

The strips ofmetal may be supplied without the flanges, as the flanged strips are only used in connection with the wood furniture placed around the form. In using the flanged strip, the sharp edges of the bulges at the bottom of the strip prevent it from working-up on that side, and the flange at the top of the strip prevents the wood furniture from working-up on that side.

Instead of the bulges and grooves, the face of the metal strips may be prepared in any other form, or suitable manner, to present a slightly greater width at the bottom in order to counteract the tendency of the form to arch, or buckle.

The invention may be applied in pages of type, monotype, or linotype slugs, where springing or arching is in evidence, or in smaller inside units where a similar condition prevails; also between sections in forms in order to keep the furniture against the bed of the press.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a device of the class described, comprising a liner for printing forms embodying a metallic strip for spacing and holding the slugs thereof, and including retaining and spacing means formed on opposite ends thereof, said means comprising a bent upper section and a punched out section formed adjacent the lower end thereof.

2. In a device of the class described, comprising a liner for printing forms embodying a metallic strip for spacing and holding the slugs thereof, and including retaining and spacing means formed on opposite ends thereof, said means comprising a bent upper section and a punched out section formed adjacent the lower end thereof, the lower end section including a spacing bead formed below said punched out section.
